Asus RT-AC1200G+ limiting bandwidth

[Krkec]

I have a problem with RT-AC1200G+ because it is limiting internet connection bandwidth. I have optic internet connection with 80 Mbps. I was testing wired and wifi connection.
With RT-AC1200G+ my download is 18 Mbps and with out is 79 mbps.

before this router i had mikrotik without any problem.

Thanks for help in advance.

Have you factory default reset the router and tested with minimal configuration?
